I agree, make an offer to pay in 2-3 month installments and make sure you get in writting that they will delete the account when you are done.
I cannot stress this enough, GET IT IN WRITTING.
I think using the "take you to court" is a scare tactic to get you to pay the account.
Did sears call you are a CA posing as sears?
If it was a CA threatening you with court is illegal.
Make that payment directly to sears and not the CA in that case make sure sears transmits the info to any and ALL CA's, often they will send it to one CA then they will send it to another and so on until you have numorous CA's all with different pay offs.
